throughout the upper surface decidedly sparser than in the normal 

 forms ; with the discovery of the male they may possibly be found 

 to represent a closely allied species. 



MELOID^E. 



ZONITIS Fab. 

 Nemognatha 111. ; Gnathium Kirby. 



Z. dnnniana n. sp. — Robust, convex, subparallel, polished, glabrous, 

 pale flavo-testaceous throughout, the antennae except at base and the tarsi 

 toward apex piceous-black. Head subtriangular, somewhat coarsely, very 

 densely punctured anteriorly, sparsely and unevenly so behind ; labrum 

 large, as long as wide ; eyes moderate, the anterior emargination distinct ; 

 antennas very slender, filiform, one-half as long as the body in the male, 

 much shorter in the female. Proihorax nearly as long as wide, just visibly 

 and evenly decreasing in width from base to apex ; sides nearly straight in 

 the middle ; base slightly wider than the apex, both equally evenly and feebly 

 arcuate ; disk rather convex, not distinctly impressed, the punctures rather 

 small, very feeble and excessively sparse. Scutellum impunctate toward apex. 

 Elytra scarcely twice as long as wide, three-fourths to four-fifths wider than 

 the prothorax, subparallel, abruptly and broadly rounded behind ; disk con- 

 vex, extremely coarsely, deeply and exceedingly sparsely punctured, each 

 with three fine feebly elevated conspicuous subcostiform lines. Legs rather 

 short and stout, the outer spur of the hind tibiae robust, compressed cylindri- 

 cal and very obliquely truncate, the inner spur a little less robust but similar 

 to the outer. Length 7.5-12.5 mm. ; width 3.2-5.8 mm.

Although belonging near punctipennis Lee, this unusually in- 

 teresting and aberrant species is distinguishable at a glance by its 

 much coarser and sparser punctures, which are fully as distant as in 

 immaculata and rather larger; it is further distinguished by the 

 remarkable disparity in size of the sexes, the male being very much 

 larger than the female. The abdomen of the male is finely, exces- 

 sively densely punctuate and dull throughout every part of its sur- 

 face, while in the female it is uniformly and unusually sparsely 

 punctuate and polished ; it is thus seen — in common with immacu- 

 lata — to be closely allied to bilineata and others of that group. 

 The maxillary processes are a little less than one half as long as 

 the head. 



Z. perforata n. sp. — Moderately slender, convex, shining, pale ochreous- 

 flavate, the elytra a little darker, brownish-rufous ; antennae black except at 

 base ; legs pale, the femora at tip, tibiae along the external edge and towarc
